摘要

虽然有关于福尔马林储存对桡足动物体型影响的定量研究，但没有关于乙醇储存的可比数据。我们测定了Parvocalanus crassirostris (Dahl, 1894)成年标本在96%乙醇中保存不同时期的收缩程度。在新鲜标本和乙醇初次保存后7、15、30和60天，分别对50只雌性和50只雄性的染色体进行了测量。尽管不同标本之间存在差异，但没有明显的收缩(P >0.05)。对于女性，显著萎缩(平均-4.2%;P, lt;0.05)，此后无显著变化。

Effect of ethanol preservation on prosomal length of the calanoid copepod Parvocalanus crassirostris (Dahl, 1894)

Abstract Although there are quantitative studies of the effect of formalin storage on copepod body size, no comparable data exist concerning storage in ethanol. We determined the degree of shrinkage of adult specimens of Parvocalanus crassirostris (Dahl, 1894) preserved in 96% ethanol for different periods of time. Measurements of the prosome of 50 females and 50 males were undertaken in fresh specimens and 7, 15, 30, and 60 days after initial preservation in ethanol. Despite variation among specimens, no significant shrinkage (P > 0.05) was detected on average males. For females, significant shrinkage (mean –4.2%; P < 0.05) was observed after seven days, with no further significant change thereafter.
